CORS is preventing the request about github-calendar

[ghjansen]

This issue is happening again.

Going to close this for now. The solution is to use a custom proxy if you don't want to depend on the default proxy.

@IonicaBizau any directions on how to do that?
There are free alternative proxies that can be used?
This issue is a big downside when using your project.

[IonicaBizau]

In the latest releases I implemented the new proxy from @Bloggify. Currently there are no max quotas, but using the default cache is recommended.

@izuzak Can you please take a look at this?

@vvzen In the meantime, you can setup a different proxy, following the docs. Urlreq is just the default one.

And because that response doesn't have the CORS headers, the error appears in the browser.
To reproduce, open: https://urlreq.appspot.com/req?method=GET&url=https://github.com/IonicaBizau

Problem solved, then 😄 You can spin up your own instance of that server (the code is open source) and buy additional quota for yourself.

I'm having the qouta problems described in this thread but i'm uncertain how to implement the solutions talked about. could someone explain to me in more detail what the exact workaround for this is? When I tried use the proxy method above, It didn't solve my problems.

@izuzak Can you please take a look at this?

@IonicaBizau Happy to take a look when I find a moment. Can you please open an issue with clear steps to reproduce? 🙏

[IonicaBizau]

Well, actually it's because Over Quota 🙈

Over Quota
This application is temporarily over its serving quota. Please try again later.

And because that response doesn't have the CORS headers, the error appears in the browser.
To reproduce, open: https://urlreq.appspot.com/req?method=GET&url=https://github.com/IonicaBizau

[IonicaBizau]

Indeed 😅

To whom it might concern, @Cipher-Coder did a great step-by-step on how to get izuzak/urlreq running through Google Cloud. See it in full at izuzak/urlreq#6.

Despite the moderate complexity of this workaround, it seems that a better solution is still much needed. Thoughts?

[IonicaBizau]

I remember I saw a pretty nice proxy service, but I don't remember its name and since I really enjoyed using @izuzak's tool, I just decided to use it.

The library accepts the proxy option:

GitHubCalendar(".calendar", "your-username", {
  responsive: true,
  proxy: function (url) {
      return "https://the-proxy-domain.com/req?method=GET&url=" + url;
   }
});

The url returned by the proxy function can be any endpoint from your server side of your app (e.g. a php file or Express endpoint etc).

I'm also confirming that urlreq.appspot.com is under "Over Quota". izuzak/urlreq#7

its back up again. I'd still love a more detailed explanation on how to use a custom proxy or to acquire more qouta.
